Note that I still have 5 bars and it was working seconds before. It's like the network just gets hung up and I end up turning my phone off then back on and it works. Is anyone else experiencing this problem? Could it be a defect or just Verizon's fault? I don't want to reboot my phone every time I want to use the Internet.
